Apparatus for shredding documents comprising two rollers driven at the same peripheral speed and in opposite directions is characterized in that the coacting peripheral surfaces of the rollers are arranged to produce in documents fed therebetween longitudinal closely-spaced folds alternately in opposite directions and, simultaneously, longitudinal tearing of the documents between each two series of two adjacent opposite folds so that the documents are delivered from the apparatus in the form of narrow folded strips having jagged longitudinal edges. In one form, rollers 1, 2 mounted on shafts 3, 4 are formed with screw threads 5, 6 of opposite pitch. The rollers are moulded from thermoplastic or thermosetting resins. The shafts, which may be driven from a crank handle or an electric motor, are carried at their ends in flanges rigid with the vertical side walls of a casing 11, Fig. 1, fitting on the top of a waste-paper basket 12. The casing has a feed slot 13 and an aperture 14 for documents not to be shredded. When a paper sheet 20 is fed through the slot 13, it is pleated by the screw threads 5, 6 and tensioned between the edges 5a, 6a of the screw threads so that it is torn in a zone 21. The sheet is thereby cut into strips each having the form shown in Fig. 6. The screw thread may be replaced by circular grooves having triangular or trapezoidal bases. The rollers may have roughened surfaces. The apparatus may comprise means for pre-treating the documents. In a modification, Figs. 7-10 (not shown), the apparatus has a trough-like casing enabling it to be fastened along one side of the top of a desk.

Abstract: 840,518. Washing machines. ROTHENBERGER, J. Oct. 25, 1957 [Oct. 26, 1956], No. 33321/57. Class 138 (2). A washing machine with at least one cylinder, a heating device, and an open overflow is used in a process in which the water supply is continuous while wetting and rinsing, and intermittent during the washing part of the cycle. As shown, during the wetting period A the solenoid controlled water supply valve is fully on (Fig. 6) while an electric heater is off (Fig. 7). At the beginning of the washing cycle B, the rotation of a cam 20 changes over contacts 21, de-energizing the solenoid valve and energizing the water heater. When the water reaches its working temperature, which may be 50- 100‹ C. for goods to be boiled, 40-60‹ C. for coloureds and 30-40‹ C. for woolens and manmade fibres, contacts 21 are again reversed and for a short interval the heater is turned off and the cold water supply is turned on. Regular reversal of contacts 21 is effected by cam 20 for the rest of the washing period of the cycle, alternately actuating the fresh water solenoid and the heater. During the rinse stage C, the heater is off and the water supply is on. After rinsing there may be provision for a spin-drying period. The Specification also includes (Fig. 5, not shown) a brief description of a machine which comprises a horizontal cylinder rotating in an enclosed tank, provided with a supply of fresh water controlled by a ball float valve to ensure constant pressure.

Abstract: 1433607 Iron doped lithium niobate crystals RCA CORPORATION 17 July 1973 [30 Oct 1972] 33977/73 Heading C1A A crystal useful for recording phase holograms comprises a single crystal of lithium niobate containing up to 0À1 mol. per cent of iron, wherein from half to almost all of the iron present is in the divalent state and wherein substantially all of the visible optical absorption is derived from divalent iron. A method used for reducing iron in an iron doped lithium niobate crystal, without substantially reducing the lithium niobate, comprises surrounding an iron doped lithium niobate crystal in a high melting salt of lithium and heating at a temperature of at least 400‹ C. in an oxygen containing atmosphere. It is preferred to heat the crystal in an atmosphere of oxygen at a temperature within the range 400-1000‹ C., the optimum temperature being dependent on the amount of iron present in the crystal. Lithium carbonate in powder form is the preferred lithium salt, but the silicate, oxide and fluoride can also be used, and the lithium salt surrounds the lithium niobate crystal while heated in a platinum crucible.
